Option b is correct. When an overridden method is called from within a subclass, it will always refer to the version of that method defined by the subclass.
Subclasses are classes that can be created by adding new functionality to a parent class, such as new object variables or new methods. In terms of automata theory, a subclass expands the state transition table with new rows and states. However, by overriding (changing) existing functionality, the majority of OO programming languages also enable us to derive subclasses from parent classes. When implementing a class, all that is required to be specified is the new or updated functionality thanks to inheritance mechanisms between parent class and subclass.
Lines connected through a circle connect the subclasses HourlyEmployee and SalaryEmployee to the superclass Employee. The circled letter "d" stands for disjointness, which demands that the specification's subclasses be distinct. As a result, an entity can belong to only one of the specification's subclasses. An individual employee can only be paid either hourly wages or a salary; they cannot be paid both. The open sides of the inheritance (arch) symbols face the superclass.

Answer:
Contiguous
Explanation:
A Contiguous memory allocation is known to be a classical memory allocation model. In this situation, we have a system which assigns consecutive memory blocks to a process. It is one of the oldest methods of memory allocation. If the process is in need of execution, the memory would be requested by the process. The processes size would then be compared to the amount of Contiguous memory that is available for the execution of the process.

Answer:
Smart
Explanation:
The RFID or the radio frequency identification is an electronic device that stores information electronically. It stores and makes available the information which is stored electromagnetically, once the user is authenticated.
This technology is implemented in market places and other individual activities. It is implemented in cards called smart card for ease of payment transaction and promote online commerce (e-commerce). It is also implemented in smartphones.
